Unable to build sample for T31 with GCC version 5.4.0 #113

Closed arshanawais closed 11 months ago

arshanawais commented 11 months ago

While trying to build sample for T31, I encounter below error(s) due to unsupported C flags. I am trying to build the sample with cross compiler GCC version 5.4.0 and I cannot use some later version because the T31 SDK/libraries I have are already built with 5.4.0 version. I also could not find a way to remove the troublesome flag from cmake files. Below is the output of build failure:

Looks like we introduced stringop-overflow in recent changes. I will roll back this change for now

codingspirit commented 11 months ago

Hi @arshanawais , I roll back webrtc sdk version to v1.8.1. Please use b998960 and try again

arshanawais commented 11 months ago

I am now able to build the sample. Thanks a lot for the changes you made.
